Title:
GAS PATH SYSTEM FOR GAS BEARING, AND MICROTURBINE
Document Type and Number:
WIPO Patent Application WO/2023/051159
Kind Code:
A1
Abstract:
A gas path system for a gas bearing (100). The gas path system comprises a gas source gas path (A), a gas supply gas path (B), a bearing gas path (C) and a buffer tank (200), wherein an input end of the bearing gas path (C) is in communication with the buffer tank (200), and an output end of the bearing gas path is in communication with the gas bearing (100); an input end of the gas source gas path (A) is in communication with an external gas source (300), an output end of the gas source gas path is in communication with the buffer tank (200), and the gas source gas path (A) is used for supplying gas to the gas bearing (100) by means of the buffer tank (200) when the gas bearing (100) is in a static pressure working mode or switched from a dynamic pressure working mode to the static pressure working mode; and an input end of the gas supply gas path (B) is in communication with a gas supply gas source (400), an output end of the gas supply gas path is in communication with the buffer tank (200), and the gas supply gas path (B) is used for supplying gas to the gas bearing (100) by means of the buffer tank (200) when the gas bearing (100) is switched from the static pressure working mode to the dynamic pressure working mode. Further provided are a control method of the gas path system for the gas bearing (100), and a microturbine comprising the gas path system. By means of providing the buffer tank (200) and the gas supply gas path (B), the gas path system can realize smooth switching of the gas bearing (100) from "the static pressure working mode" to "the dynamic pressure working mode", thereby ensuring the stability of the working state of a rotor.
